Skin Tags
Skin tags, or dermatofibromas, are fleshy, pedunculated growths that can occur anywhere, but most often arise on the neck, axillae, or groin area. They are usually removed with electrodessication or with a scalpel or scissors. Frequently, local anesthesia is used for this procedure. Because skin tags generally occur in clusters, and are simple to remove, they are coded separately from the destruction of other types of skin lesions. The CPT? 11200 Removal of skin tags, multiple fibrocutaneous tags, any area; up to and including 15 lesions code for skin tag removal includes the first 15 lesions removed. The CPT? +11201 ? each additional 10 lesions (List separately in addition to code for primary procedure) code is used for each additional 10 lesions. For example, if 25 lesions are removed, code both 11200 and 11201.

I believe that is out of date since it was published in 2008. My coding teacher was explaining that a couple years ago, AMA added "part thereof" to the description of some codes because there was too much confusion on what to do if it was more than the base code and not enough for the add-on code.

If you do 16 you can still bill 11200 & 11201
If you do 38 you can still bill 12000 & 12001x3
